Humboldt Bay Trail


When complete, the 13-mile long Humboldt Bay Trail will run from south Eureka through Arcata, serving as an anchor for a network of adjacent trails that connect surrounding communities. This non-motorized trail will increase road safety, provide a low-cost travel alternative, expand recreational opportunities, improve community livability, and promote active, healthy transportation. The trail is being constructed in phases by the cities of Eureka and Arcata and Humboldt County. Construction funding is secured for all but the final four miles of the trail, a section called “Bay Trail South” that extends from Target to Bracut Industrial Park.

Partnerships For Trails

Three local agencies are currently leading the development of segments of the Humboldt Bay Trail:
  1. County of Humboldt
  2. City of Arcata
  3. City of Eureka

Humboldt County is leading the development of the Humboldt Bay Trail South segment which will provide the interconnecting link between Eureka’s and Arcata’s trail projects. The project area extends from the Bracut Industrial Center to X Street in Eureka near the Target store, for a total length of 3.8 miles.

The County was allocated funds through the State Transportation Improvement Program to complete preliminary engineering, environmental studies, and permitting and to develop engineering plans and specifications for the Bay Trail South segment. Preliminary cost estimates for right-of-way and construction range from $9 to $12 million. Costs for environmental mitigation are estimated at $1.5 to $2.0 million.  Future funding will need to be secured for these components. The goal is to have engineering plans, funding and permits in place to initiate construction by 2021.

The Humboldt Bay Trail Fund

The Humboldt Bay Trail Fund was established at the Humboldt Area Foundation to provide a mechanism for private donors to assist in the continued development of the Humboldt Bay Trail by focusing on the critical need for trail maintenance funds. The fund will give priority to on-going emergency trail maintenance with emphasis on supporting volunteer efforts. Make an on-line donation!

Project Documents

Humboldt Bay Trail North Historic Property Survey Report (September 2015) – This report evaluates potential historic resources within the project area for the City of Arcata’s Bay Trail North project.

Historic Resources Evaluation Report : Eureka to Arcata Route 101 Corridor Improvement Project, Humboldt County, CA (July 2004) – This report evaluates potential historic resources along the Eureka to Arcata highway corridor. (excerpt only) 

Preliminary Surveying Analysis of Railroad Right-of-way, Northwestern Pacific Railroad Co., Eureka to Arcata (around Humboldt Bay) (February 26, 2015) - This report contains the results of an analysis of deeds associated with the right-of-way of a portion of the Northwestern Pacific Railroad around Humboldt Bay between Eureka and Arcata. The purpose of the study was to develop a master list of deeds that define the railroad right-of-way within the project area, and to identify the location and extent of the parcels referenced in the deeds.  This file contains the report text, figures, and tables (no attachments).

Botanical Report (September 17, 2014) - This report documents the results of a survey for special status plants within the project area.

Initial Engineering Study (August 2014) - This report provides a detailed evaluation of alignment options within the project area.  Alignment options generally include “rail-with-trail” (trail closer to the railroad) and “highway-with-trail” (trail closer to the highway) segments.  The Initial Engineering Study is a technical support document and does not identify a preferred or recommended alignment.  

Project Study Report (March 18, 2014) - This report provides a general overview of the project including background and history, purpose and need, planning and design issues, and alternatives.

Humboldt Bay Trail Project Update Brochure (June of 2014) - This brochure was produced to provide details about project history, goals, and status.
